Electrical conductivity measurements on dry and hydrous melts plotted in Arrhenius diagrams. The straight lines indicate the fits of the P–T–H2O model (Eqs. (1)–(4)). P is the pressure (GPa), w is the water concentration (wt%). a Experimental results for nominally dry samples at different pressures. b Experimental results for different water concentrations at ~1 GPa or ~2 GPa
